One of the first things that I do upon receiving a new Windows computer is I create my own custom boot menu that shows up every time I boot my machine.

This is especially handy when you suspect a virus or a failed installation that corrupted your registry; you can reboot into safe mode and scan for it. It is easy to create a custom boot menu for yourself, and it is so worth it.

Description of boot.ini

  • The timeout variable specifies how long Windows waits before choosing the default operating system.
  • The default variable specifies the default operating system.

  • The term scsi(0) means that the primary controller (that is frequently the only controller) is responsible for the device. If there are two SCSI controllers, and the disk is associated with the second controller, the controller is named scsi(1). If the system uses IDE, enhanced IDE (EIDE), or Enhanced Small Device Interface (ESDI) drives, or if the system uses a SCSI adapter that does not have a built-in BIOS, replace scsi with multi.

  • The term disk(0) refers to the SCSI logical unit (LUN) to use. This may be a separate disk, but most SCSI setups have only one LUN for each SCSI ID.
  • The term rdisk(0) refers to physical disk 1.
  • The term partition(1) is the partition on the first drive in the computer. If there are two partitions, partition C is partition(1) and partition D is partition(2).
  • A multi-boot parameter calls for checking the Winnt folder to start from a specified SCSI controller’s disk and partition.
  • /NODEBUG specifies that no debugging information is being monitored. Debugging information is useful only for developers.
  • You can add the /SOS option to display driver names while the drivers are being loaded. By default, the OS Loader screen only shows progress dots.
  • Previous Operating System on C:\ implies that the previous operating system is MS-DOS, because C:\ is an MS-DOS path.

  2. Press F8 when prompted.

    after the firmware POST process completes but before Windows XP displays graphical outputNOTE: If Windows XP Professional starts without displaying the menu shown above, restart your computer. Press F8 after the firmware POST process completes but before Windows XP displays graphical output like the image on the right.

If you can’t boot windows or recovery console after you edit the boot.ini

Start the computer from the Windows XP CD, start the Recovery Console, and then use the Bootcfg.exe tool to rebuild the Boot.ini file. To do this, follow these steps:

  1. Configure the computers bios to boot from the CD-ROM or DVD-ROM drive.
  2. Insert the Windows XP CD-ROM into your CD-ROM or DVD-ROM drive, and then restart your computer.
  3. When you receive the “Press any key to boot from CD” message, press a key to start your computer from the Windows XP CD-ROM.
  4. When you receive the “Welcome to Setup” message, press R to start the Recovery Console.
  5. If you have a dual-boot or multiple-boot computer, select the installation that you have to use from the Recovery Console.
  6. When you are prompted, type the administrator password, and then press ENTER.
  7. At the command prompt, type bootcfg /list, and then press ENTER. The entries in your current Boot.ini file appear on the screen.
  8. At the command prompt, type bootcfg /rebuild, and then press ENTER. This command scans the hard disks of the computer for Windows XP, Microsoft Windows 2000, or Microsoft Windows NT installations, and then displays the results. Follow the instructions that appear on the screen to add the Windows installations to the Boot.ini file. For example, follow these steps to add a Windows XP installation to the Boot.ini file:
  • When you receive a message that is similar to the following message, press Y:
  • Total Identified Windows Installs: 1

    NOTE: The instructions that appear on your screen may be different, depending on the configuration of your computer.
  • Type exit, and then press ENTER to quit Recovery Console. Your computer restarts, and the updated boot list appears when you receive the “Please select the operating system to start” message.

How to Hide Boot.ini Entries from Displaying

You can hide additional installations of Windows from being displayed in the boot menu, but still gain access to them when you need to.

To hide menu items from the Boot.ini file, so they will not be accessible:

  1. Remove the read-only attribute from the Boot.ini file.
  2. Use an editor to edit the Boot.ini file.
  3. Place the following entry above the lines you want hidden: 
    [any text].
This will hide all entries below the [any text] heading.
  4. To restore the entry and make it accessible again, remove the [any text] line.
  5. Save the file and reapply the read-only attribute.
  6. Restart your computer.

For example, the 3 bottom entries below will not be displayed or accessible the next time the system is restarted. Simply remove [any text] to gain access to this installation.

Boot.ini Switches

You can add many different switches to the Boot.ini file that will modify the way that Microsoft Windows starts.

  1. /basevideo The /basevideo switch forces the system into standard 640×480 16-color VGA mode by using a video driver that is compatible with any video adapter. This switch permits the system to load if you select the wrong video resolution or the wrong refresh rate. Use this switch in conjunction with the /sos switch. If you install a new video driver, and it does not work correctly, you can select the Windows 2000 entry with this switch to start the computer and to change to a different driver.
  2. /baudrate=number This switch sets the baud rate of the debug port that is used for kernel debugging. The default baud rate is 9600 kilobits per second (Kbps) if a modem is attached. The default baud rate is 19200 Kbps for a null-modem cable. 9,600 is the normal rate for remote debugging over a modem. For example, type /baudrate=9600 to specify a baud rate of 9600. If this switch is in the Boot.ini file, the /debug switch is automatically enabled.
  3. /crashdebug This switch turns on the COM port for debugging when Windows 2000 crashes. /crashdebug is useful if you experience random kernel errors. With this switch, you can use the COM port for normal operations while Windows is running. If Windows crashes, the switch converts the port to a debug port. (This action turns on remote debugging.)
  4. /debug This switch turns on the kernel debugger when you start Windows. The switch can be activated at any time by a host debugger that is connected to the computer, if you want to turn on live remote debugging of a Windows system through the COM ports. Unlike the /crashdebug switch, /debug uses the COM port whether you are debugging or not. Use this switch when you are debugging problems that are reproducible.
  5. /debugport=comnumber This switch specifies the communications port to use for the debug port, where number is the communications port, such as COM1, that you want to use. For example, type /debugport=com1, where the com port is COM1. By default, /debugport uses COM2 if it exists. Otherwise, the switch uses COM1. If you include this switch in the Boot.ini file, the /debug switch becomes active.
  6. /maxmem=number This switch specifies the maximum amount of RAM that Windows can use. Do not make this setting less than 12. Use this parameter to confirm whether a memory chip is faulty.
  7. /nodebug This switch turns off debugging. This switch can cause a Stop error if a program has a debug hardcoded breakpoint in its software.
  8. /numproc=number This switch sets the number of processors that Windows will run at startup. With this switch, you can force a multiprocessor system to use only the quantity of processors (number) that you specify. This switch can help you troubleshoot performance problems and defective CPUs.
  9. /pcilock For x86-based systems, this switch stops the operating system from dynamically assigning hardware input, hardware output, and interrupt request resources to Peripheral Connect Interface (PCI) devices. With this switch, the BIOS configures the devices. NOTE: In earlier versions of Windows, including Windows NT 4.0, this switch was named /noserialmice.
  10. /fastdetect:comnumber This switch turns off serial and bus mouse detection in the Ntdetect.com file for the specified port. Use this switch if you have a component other than a mouse that is attached to a serial port during the startup process. For example, type /fastdetect:comnumber, where number is the number of the serial port. Ports may be separated with commas to turn off more than one port. If you use /fastdetect, and you do not specify a communications port, serial mouse detection is turned off on all communications ports.
  11. This switch is also used with uninterruptible power supplies (UPS), such as those supplies from American Power Conversion brand (APC), that connect to a serial port. If this switch is not available when Windows starts, and Windows tries to detect a mouse on this port, the UPS incorrectly starts its shutdown mode. NOTE: In earlier versions of Windows, including Windows NT 4.0, this switch was named /noserialmice.
  12. /sos The /sos switch displays the device driver names while they are being loaded. By default, the Windows Loader screen only echoes progress dots. Use this switch with the /basevideo switch to determine the driver that is triggering a failure.
  13. /PAE Use the /PAE switch with the corresponding entry in Boot.ini to permit a computer that supports physical address extension (PAE) mode to start normally. In Safe Mode, the computer starts by using normal kernels, even if the /PAE switch is specified.
  14. /HAL=filename With this switch, you can define the actual hardware abstraction layer (HAL) that is loaded at startup. For example, type /HAL=halmps.dll to load the Halmps.dll in the System32 folder. This switch is useful to try out a different HAL before you rename the file to Hal.dll. This switch is also useful when you want to try to switch between starting in multiprocessor mode and starting in single processor mode. To do this, use this switch with the /kernel switch.
  15. /kernel=filename With this switch, you can define the actual kernel that is loaded at startup. For example, type /kernel=ntkrnlmp.exe to load the Ntkrnlmp.exe file in the System32 folder. With this switch, you can switch between a debug-enabled kernel that is full of debugging code and a regular kernel.
  16. /bootlog This switch turns on boot logging to a file that is named systemroot\Ntbtlog.txt. For more information about boot logging, see Windows Help.
  17. /burnmemory=number This switch specifies the amount of memory, in megabytes, that Windows cannot use. Use this parameter to confirm a performance problem or other problems that are related to RAM depletion. For example, type /burnmemory=128 to reduce the physical memory that is available to Windows by 128 MB.
  18. /3GB With this switch, user mode programs can access 3 GB of memory instead of the usual 2 GB that Windows allocates to user mode programs. The switch moves the starting point of kernel memory to 3 GB. This switch is used only with Windows 2000 Server Enterprise Edition. Some configurations of Microsoft Exchange Server 2000 and Microsoft Windows 2000 Advanced Server may require this switch.
  19. /safeboot: This switch causes Windows to start in Safe Mode. This switch uses the following parameters:
    • /safeboot:minimal/sos/bootlog/noguiboot This switch starts Windows in Safe Mode.
    • /safeboot:network/sos/bootlog/noguiboot This switch starts Windows in Safe Mode with networking.
    • /safeboot:minimal(alternateshell)/sos/bootlog/noguiboot This switch starts Windows in Safe Mode with a command prompt.
    • /safeboot:dsrepair/sos On domain controllers only, this switch starts Windows in Directory Services Restore Mode.
  20. NOTE: The /sos,/bootlog, and/noguiboot switches are not required with any one of these settings, but the switches can help with troubleshooting. These switches are included if you press F8 and then select one of the modes.
  21. /userva Use this switch to customize the amount of memory that is allocated to processes when you use the /3GB switch. This switch permits more page table entry (PTE) kernel memory but still maintains almost 3 GB of process memory space. NOTE: Microsoft Product Support Services strongly recommends using a range of memory for the /USERVA switch that lies within the range of 2900-3030. This range is wide enough to provide a large enough pool of system page table entries for all currently observed issues. Usually a setting of /userva=2900 will provide close to the maximum available number of system page table entries possible.
  22. /redirect Use this switch to turn on Emergency Management Services (EMS) on a Windows Server 2003, Enterprise Edition-based computer. For additional information about EMS, search on “Emergency Management Services” in Windows Help and Support.

Adds operating system load options specified as a string to an operating system entry in the [operating systems] section of the Boot.ini file.

Syntax

BOOTCFG [/s Computer [/u Domain\User /p Password]] /raw OSLoadOptionsString [/id OSEntryLineNum]

NOTE: Bootcfg raw is used to add text to the end of an operating system entry, overwriting any existing operating system entry options. This text should contain valid OS Load Options such as /debug, /fastdetect, /nodebug, /baudrate, /crashdebug, and /sos. For example, the following command adds “/debug /fastdetect” to the end of the first operating system entry, replacing any previous operating system entry options:
BOOTCFG /raw “/debug /fastdetect” /id 1

Examples

BOOTCFG /raw "/debug /sos" /id 2
BOOTCFG /raw /s srvmain /u maindom\hiropln /p p@ssW23 "/crashdebug " /id 2

BOOTCFG rmsw

Removes operating system load options for a specified operating system entry.

Syntax

BOOTCFG /rmsw [/s Computer [/u Domain\User /p Password]] [/mm] [/bv] [/so] [/ng] /id OSEntryLineNum

Parameters

  1. /mm Removes the /maxmem switch and its associated maximum memory value from the specified OSEntryLineNum. The /maxmem switch specifies the maximum amount of RAM that the operating system can use.
  2. /bv Removes the /basevideo switch from the specified OSEntryLineNum. The /basevideo switch directs the operating system to use standard VGA mode for the installed video driver.
  3. /so Removes the /sos switch from the specified OSEntryLineNum. The /sos switch directs the operating system to display device driver names while they are being loaded.
  4. /ng Removes the /noguiboot switch from the specified OSEntryLineNum. The /noguiboot switch disables the Windows XP Professional progress bar that appears before the CTRL+ALT+DEL logon prompt.

Examples

BOOTCFG /rmsw /mm 64 /id 2
BOOTCFG /rmsw /so /id 3
BOOTCFG /rmsw /so /ng /s srvmain /u hiropln /id 2
BOOTCFG /rmsw /ng /id 2

BOOTCFG timeout

Changes the operating system time-out value.

Syntax

BOOTCFG /timeout TimeOutValue [/s Computer [/u Domain\User /p Password]]

Parameters

  1. TimeOutValue Specifies the timeout value in the [boot loader] section. The value is the number of seconds the user has to select an operating system from the boot loader screen before NTLDR loads the default. If the value is 0, then NTLDR immediately starts the default operating system without displaying the boot loader screen.

Examples

BOOTCFG /timeout 30
BOOTCFG /s srvmain /u maindom\hiropln /p p@ssW23 /timeout 50
